Specification of Letters Patent.

To all wom t may concern.

Be it known that l, FRED CHEVALIER, a citizen of the United Stat-es of America, and a resident oflVatei-loo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Antifriction-llf'heels, of which the following is a specification.

My invention relates to improvements in antifriction Wheels, and particularly to carwheels, and the object-of my improvement is to furnish easily operated means for introdueing the anti-friction balls into the raccway of the wheel parts, and constitutes an improvement on the anti-friction wheel which was patented by me in the United States, Number 1,176,342, dated March 2l, 1916.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Figure 1 is a cross-scction of one half ot' a ear-wheel containing my improved means for introducing anti-friction balls into the raeeway between the parts of the wheel; Fig. Q is a fragmeutal side elevation of the same part of the'wheel showing the closure-block in place; F ig. 3 is an elevation of the outer face of a wheel of the type mentioned, with parts broken away to disclose the reiintrant cavity or seat for said closure-block; Figs. l and 5 are perspective detail Views of said closure-block, as seen from different sides, and Fig. 6 is a perspective View of the special locking bolt employed to secure Said closure-block removably in its seat.

Similar numerals of reference denote corresponding parts throughout the several views.

The numeral 3 denotes a solid center casting for the annular wheel-rim 4, mounted concentrically therein, said center and rim having annularly mated raceway grooves providing a ball raceway 5 to contain antivfriction balls 6, and the center` Si is lixedly mounted on the squared extremity 2 of a relatively fixed axle l.

'lhe center 3 has a sloping rccutrant port or passage with a shallow curved bottom groove 8 leading into the raceway 5 to guide thel balls t3 to enter the raccu'av from without in succession. l have furnished a removableclosure-block lil to lill said reiintlanl. jat 7, having an inclined inner l'ace uith raised curved rib li to lit` said seat. and its groove 8 when the block is in placelhe opposite sides of the block 13 are Hat and parallel so as to tit removably the like sides of said seat 7, so that the block can be placed in the seat or .vithdrawn therefrom veasily and without interference in any Way.

The block has a transverse orifice 18 through which a liquid lubricant may be introduced, and also a transverse bolt-hole 19 registering with a like bolt-hole in the center 3 to receive a fastening bolt Q8 provided wit-h a nut 25.

In order to lock the elosure-block securely in place l have provided the following securing-means in addition to said bolt 23. The opposite side-walls ot' the seat 7 have transverse rectangular grooves l2 positioned opposite like transverse rectangular grooves in the side-walls of said block 13 as shown at 1G, which thus furnish a pair of rectangular seats for the squared shanks 2l of the bolts 20. the latter having securing nuts 2l. rlhe outer ends of said rectangular seats are rcctangularly widened at 17 in both the center 3 and the block i3, to admit the rectangularly widened heads of the bolts 20 llush with the outer face ot' said center 3.

After balls t3 have been passed into the raceway b v way of the. reentrant passage '3, the block 13 is fitted into the said passage flush with the outer it'ace of said Center 3, the bolts :223 and Q() fitted in their seats and secured by means of their respective nuts 25 and 24A. it will be seen that, the squared heads and shanks of the bolts Q0 will lock the block i3 in its seat against any movements relative to the center 3, under the jars of transit, and are easily placed or removed when desired. 'lhe to of the bloei-:'13 has a concave groove l5 orining part of said raeewajv, and into which the inner end of the channel 1S for passage of lubricant opens.

To keep dust from entering the raeeway, l provide arc-shaped bars 26 to cover the out nai-diy opening spaces between the center 3 and the rim Al, supported removably on eurrier-bars 2T. the latter secured removably to the center 3. lt will be seen that when all said parts are assembled and secured in the manner described`r the wheel center being fixed has the. rim -l rotatable around it, and thus serves tor means of transportation for a. car or vehicle.

My improved type ol' anti-friction wheels are not only adapted for use on railway cars, but are especially tilted for employment in MEP trucks, hand or power actuated, various vehicles, and in other applications such as will be obvious to those skilled in the art. The engaging-means for the closure-block may be modified in form and dimensions without departing from my invention.

Having described my invention, what I claim as new, 'and desire to secure by Letters Patent, is:

1. An anti-friction Wheel, comprising a relatively fixed center body, an annular rim mounted rotatably therearound, said center body-and rim having registering annular concentric raceways, anti-friction balls in said raceways, said center body having a reentrant cavity leading into said raceway to conduct anti-friction balls thereinto, l a closure-block removably fitting said cavity, and means for detachably securing said block in said cavity, consisting of like angular recesses in opposed faces of the block and the cavity walls, and securing-means mounted in said recesses, to fit same and prevent shifting of the block While faste ing it removably to said center body.

2. An anti-friction wheel, comprising a l relatively fixed center body, an annular rim mounted rotatably therearound, said center body and rim having registering annular concentric raceways, anti-friction balls in Asaid raceways, said center body having a rentrant cavity with sloping inner wall leading into said raceway to conduct antifriction balls into the raceway, a closureblock removably fitting said cavity, said block having in opposite side walls transverse rectangular grooves which are widened rectangularl at their outer ends, the adjacent side Wa ls of said cavity having like grooves registering with the adjacent grooves in the block, and bolts fitted removably in said grooves, having rectangular shanks and widened heads to fit the grooves, and cylindrical extremities, the center body having bolt-holes in which the cylindrical parts of the bolts are seated, and means to fasten said bolts to the center body, the rectangular heads of the bolts being flush with the outer face of said block, and the outer face of said block being iush with the abutting outer face of said center body.

3. An anti-friction wheel, comprising a. relatively fixed center body, a rim rotatable about said body, said body and rim having raceways, anti-friction bodies movably positioned in said raceways, said body having a recess leading slopingly into its raceway adapted to permit said anti-friction bodies to'gbe passed therethroughinto and out of said raceways after the rim is mounted on said center body, a closure fitting said recess, movable into and out of same slopingly,

said closure containing part of the raceway groove therein, and means for detachably interlocking said closure with said body when seated in said recess.
